Option B: 1.6 s.
Although the equation is not included, you can obtain it by physical considerations
H(t) = -16.t^2 + 52t + 16
The maximum point is at the vertex and the vertex is in the middle of the roots.
The roots are when H(t) = 0,
So you have to solve 0 =-16t^2 + 52t + 16
Use the quadratic formula and you will find t = 3.53 and t =-0.28
Then the vertex is at the middle point = (3.53 -.028)/2 =1.63 s and the answer is option B: 1.6 s.
Answer:
y = -0.9x+10.1
Step-by-step explanation:
The equation of the line is:
You have been asked to stimate m and b. To do so, first find the product between each pair of x and y and the value of x squared:
Then calculate the total sum of all columns:
m can be calculated following the next equation:
where n is the number of (x, y) couples (5 in our case).
Replacing the values calculated previously:
For b:
In the figure attached you can see the points given and the stimated line.
Answer:
T= 4p-18-pr
Step-by-step explanation:
The correct answer is D, since a rotation of 360 has no effect, since the figure does a whole turn and returns where it was.
